Six Walls

Plugin · VST3, AU & AAX

The NanoFlux™

The non-reverb side of the original Alesis NanoVerb (unofficial) — chorus, flange, delay, gated reverb, and rotary — measured from a real unit and modeled warts and all. Plus Pawn Shop: the same box after a hard life and a previous owner’s soldering iron. Free for Windows and macOS.

The NanoFlux plugin UI: Six Walls header with a Pawn Shop button, Input, Mix, and Output knobs, a five-position mode dial set to Delay, the Adjust knob reading 1/8 with Tempo Sync ticked beneath it, grayed-out Rate and Depth knobs, POWER and SIGNAL lights, and the standard Six Walls toolbar
Before you download Six Walls is one person building these in his spare time and giving them away.

Windows: the installers are code-signed — verified publisher Edwin Jones. A fresh signing certificate takes a little while to build reputation with SmartScreen, so for the first few weeks you may still see a “not commonly downloaded” note — click More info → Run anyway.

macOS: the .pkg and the bundle .zip are signed with a Developer ID and notarized by Apple, so they open with no Gatekeeper prompt. Universal — Apple silicon and Intel.

Five programs from a real NanoVerb, each measured on the unit — sweep rates, delay times, filters, gate lengths, rotor patterns, the Mix pot’s own curve — and checked by ear against it, side by side, on real material. One Adjust knob per program, just like the hardware.

  • Chorus — true stereo: the two sides sweep at different speeds, from slow and deep to quick and subtle.
  • Flange — a feedback comb; at the bottom of the knob the sweep stops and it freezes into a fixed, metallic tone.
  • Delay — up to 1.27 s in the unit’s own 10 ms steps, or Tempo Sync: fourteen note values from 1/32 to 1/1, dotted and triplet included.
  • Non-Linear — the classic 1980s gated-reverb snare, from a tight 145 ms to a big 620 ms gate.
  • Rotary — a two-speed rotating speaker with the hardware’s quick spin-up and slow coast-down.
  • Turn Adjust all the way up for Custom Rate and Depth beyond what the front panel allows. Factory presets included, plus an Init – FX Send preset for effects channels.
  • Zero latency. Passes pluginval at strictness 10.

Pawn Shop The same box, after a few pawn shops. One button turns The NanoFlux into the bare hardware with every rough edge: crackly Input and Output pots, a slightly hot right side, chorus and flange sweeps that drift, a tired rotary motor that catches and drags, and raw delay-time jumps that splat when you move Adjust. And a Clock Mod knob drilled into the faceplate where Depth used to be — the most popular real NanoVerb circuit bend: slow the whole unit’s clock and everything stretches out darker and hissier; push it past 100 % and it starts to crackle.
The NanoFlux in Pawn Shop mode: scratched and scuffed panel, aged ivory lettering, a torn sticker, a worn Six Walls logo sticker, and a Clock Mod knob in place of Rate and Depth
